Thyroid surgery usually does not require a urinary catheter, but if the patient is older or has a prostate condition of their own, a urinary catheter will need to be inserted. There are many types of thyroid surgery, such as partial thyroidectomy, subtotal thyroidectomy, and total thyroidectomy, etc. Although general anesthesia is required for thyroid surgery, urinary catheter insertion is not routinely needed during the surgery due to the less traumatic nature of the procedure and the shorter duration of the surgery. For some patients who are older or suffer from prostate diseases themselves, such as prostatitis, prostate hyperplasia, etc., even though the operation time is shorter, in order to avoid postoperative urinary difficulties, it is therefore recommended to insert a urinary catheter before the start of the operation. To sum up, it is impossible to generalize whether a urinary catheter needs to be inserted for thyroid surgery, and patients are advised to consult their doctors in detail according to their individual conditions. After the surgery, patients need to pay attention to rest and avoid overwork.
